Specialized Stumpjumper Expert 650b Mountain Bike 2018 – Heritage Gloss Acid Mint/Acid Kiwi/Acid Pink
We built our Stumpjumper Expert 650b to be the ultimate all-rounder trail bike.
If your idea of trail riding follows the philosophy of ''go big or go home'' you simply can't beat the agility and responsiveness that a 650b wheels provide.
Knowing this we built our Stumpjumper Expert 650b to be the ultimate all-rounder trail bike.It features our FACT 9m carbon fibre for the bulk of the construction in order to provide an ultra-lightweight strong and stiff frame.
The carbon moulding process also allowed us to revolutionize how you carry your trail essentials with the all-new SWAT™ Door found at the down tube.
This compartment will fit a tube a tool and pump without rattling or compromising the structural integrity of the frame.You'll also find an aggressive nimble geometry to complement the 650b wheels that features ridiculously short chainstays a roomy top tube a low bottom bracket and a slacked out front end.
And for the build we spec'd some of SRAM's best performing and durable 12-speed components a FOX 34 Performance fork with 150mm of travel and hand-built Roval Traverse 650b carbon wheels.
It's a bike that will have you never looking back—unless it's to see your buddies eating your dust.
FACT 9m carbon fibre Trail Chassis with Stumpjumper FSR M5 alloy rear end blends stiffness with light weight to form the pinnacle of efficiency while fully enclosed cable routing and an integrated SWAT™ Door create exceptional handling and zero-hassle storage.
The FOX 34 fork features 150mm of plush travel to take on big hits and bumpy terrain with supreme confidence and efficiency.
SRAM's 12-speed GX Eagle drivetrain with a Truvativ Descendent crank features an ultra-wide gear range that delivers climbing and descending efficiency in spades.
On top of this the one-by setup is notorious for being next to impossible to drop a chain with plus it provides a significant weight savings in comparison to a standard two-by setup.FRAMEFACT 9m carbon front chassis w/ Specialized M5 Aluminum rear end 27.5 Trail Geometry SWAT™ Door integration PF30 BB fully enclosed internal cable routing 12x148mm dropouts sealed cartridge bearing pivots replaceable derailleur hanger 150mm of travelFORKFOX 34 Performance 27.5 44mm offset 15x110mm thru-axle 150mm of travelREAR SHOCKRockShox Monarch RT3 Rx Trail Tune AUTOSAG rebound and 3-position compression adjust 197x48mmFRONT HUBSpecialized sealed cartridge bearings 15x110mm spacing 24hREAR HUBSpecialized sealed cartridge bearings 12x148mm thru-axle 28hSPOKESDT Swiss Industry stainless 3-cross 2.0'RIMSRoval Traverse Carbon 27.5 hookless carbon 30mm inner width 24/28h tubeless ready hand-builtINNER TUBESStandard Presta valveFRONT TYREButcher GRID casing Gripton compound 2Bliss Ready 27.5 x 2.6'REAR TYREButcher GRID casing Gripton compound 2Bliss Ready 27.5 x 2.6'CRANKSETTruvativ Descendant aluminum Boost™ 148 170mm crankarm 30mm spindleCHAINRINGS32TBOTTOM BRACKETPF30SHIFT LEVERSSRAM GX Eagle trigger 12-speedREAR DERAILLEURSRAM GX Eagle 12-speedCASSETTESRAM GX Eagle 12-speed 10-50tCHAINSRAM GX Eagle 12-speed w/ PowerLock®FRONT BRAKESRAM Guide R hydraulic disc organic pads Guide S4 4-piston caliper 200/180mm rotorREAR BRAKESRAM Guide R hydraulic disc organic pads Guide S4 4-piston caliper 180/160mm rotorHANDLEBARSSpecialized Trail 7050 alloy 8-degree backsweep 6-degree upsweep 27mm rise 780mm 31.8mm clampGRIPSSpecialized Sip Grip half-waffle S/M: regular thickness L/XL: XL thicknessSTEMSpecialized Trail 3D forged alloy 4-bolt 6-degree riseSADDLEBody Geometry Henge Comp hollow Cr-Mo rails 143mmSEATPOSTCommand Post IRcc 12-position micro-height adjustable alien head design bottom mount cable routing remote SRL lever 30.9mm S: 100mm M/L/XL: 125mm of travelSEAT BINDERAlloy 34.9mmPEDALSSpecialized Platform Cr-Mo 9/16' spindle
